what is the main idea of the article? use evidence from the text to explain your thinking.

vitamins
the body also needs vitamins. vitamin c keeps gums healthy and helps the body absorb iron. vitamin d works with calcium and phosphorus to make strong bones and teeth. other vitamins are a, e, k and the b - complex vitamins. vitamins are found in many different foods.

water
water is important in many chemical reactions in the body. in fact, every cell in the body must be bathed in water. water also helps the body get rid of wastes and maintain its temperature. water makes up about 60 percent of an adults body weight.

the number of calories needed by people each day depends on how much energy their bodies use. for example, an athlete usually needs more calories than an adult who works at a desk all day.

nutrients
food also provides the nutrients that the body needs to function and maintain itself. these nutrients are proteins, carbohydrates, fats, minerals, vitamins and water.

proteins are needed for body tissue to grow and repair itself. after water and possibly fat, protein is the most abundant material in the human body. people can get the protein they need from animals or plants. animal sources include meat, fish and eggs. plant sources include beans, nuts and grains.

carbohydrates give the body most of the energy it needs. starches and sugars are carbohydrates. starches are found in grains such as rice, wheat and corn. potatoes, beans and other vegetables also contain starch. sugars are found naturally in fruits, milk and honey. refined sugars are made by processing plants such as sugarcane, sugar beets and corn. these sugars are often used to sweeten foods, and they are high in calories.

fiber
fiber is another kind of carbohydrate. it does not provide energy, but it is important to the body. it helps people to feel full. in addition, fiber can reduce the level of cholesterol in the blood. cholesterol is an important substance in the body. however, if the body has too much cholesterol, blood vessels may become lined with fatty deposits. the blood vessels then become narrow and stiff, which can lead to a heart attack or stroke.
